Title: Improvements in machines for timing fuses for projectiles
IPC: F42C17/00
Filed: 1934-06-13
Abstract: 424,751. Setting projectile fuzes. MEFINA SOC. ANON., Binningen, and VARAUD, A., 109, Route de Lyon, Geneva, both in Switzerland. June 13, 1934, No. 17509. [Class 9 (i)] Relates to apparatus for setting projectile fuzes of the kind described in Specifications 407,843 and 407,845. According to the present invention, a rotary driving member 15 is arranged concentrically with two other members 19, 1, one 19 for locking and coupling the projectile, and the other 1 for effecting the timing. A projectile introduced into the apparatus depresses a rod 28 connected by racks 29, 30 and pinion 31 to a spring controlled plunger 25, which is thus withdrawn and unlocks the driving disc 15 and the crown 19 thereon. The disc 15 is then rotated clockwise by means of its shaft 14; and, by means of pawls 22 on the disc in engagement with the teeth of the crown 19, the crown is made to follow the rotation and to operate the projectile locking eccentric 7 and the coupling device 3 by means of a link 12 pivoted to a lug 20 on the crown. When this double operation is completed, rods 18 attached to the timing crown 1 and traversing holes 16 in the disc 15 deflect the pawls 22 and abut against the edge of the holes. The locking crown 19 then remains in its position, while the timing crown 1 is driven round by the disc 15 until arrested by the adjustable stop determining the time required. The setting completed, the shaft 14 is rotated in the reverse direction, and the first part of this rotation is transmitted by another set of pawls 21 on the disc 15 to the crown 19 to unlock and uncouple the projectile, until the transverse rods 18 deflect these pawls and abut against the other edge of the holes 16. Continued rotation of the shaft 14 and disc 15 then drives the timing ring 1 back to zero, whereupon the plunger 25 relocks the apparatus when the projectile is removed. Slots may be formed at a pivot of the linkwork 12 to ease the co-operation of the pawls with the teeth of the crown 19. In a modification, instead of the pawls 21, 22 and the teeth on the crown 19, the crown is frictionally clamped to the disc 15 under the control of cam-like clamping devices. Both pawls and clamping devices may be provided, the latter being put in action if the pawl go out of order. The lever 11 to which the link 12 is connected may be constructed tumbler-fashion to cause the mechanism to pass to its extreme positions through a dead centre. A tumbler catch may be provided on a member rotating with the driving shaft and co-operating with a fixed part of the apparatus to compel the operator to complete the timing operation before he can turn the shaft in the reverse direction, the catch being automatically rocked in one direction or the other as the timing crown reaches the set time and the zero positions respectively.

Title: Synchronizing control apparatus for colour television
IPC: H04N9/455
Filed: 1959-05-25
Abstract: 882,234. Colour television. HAZELTINE CORPORATION. May 25, 1959 [June 20, 1958], No. 17717/59. Class 40(3). In a colour television receiver, Fig. 1, for use in the N.T.S.C. type of system the colour synchronizing "burst" signal B<SP>1</SP>, Fig. 2, which appears on the back porch P of synchronizing pulse S, is separated from the chrominance signal appearing at terminal 27 by means of a normally non-conducting gate stage 51 which is rendered conducting for a predetermined portion only of the "burst" interval by means of a gating wave derived by a stage 34 in response to linesynchronizing and fly-back pulses applied at terminals 29 and 30 respectively. The pulses M and N, Fig. 3, combine to produce a wave X at the grid of stage 34 which produces conduction during each synchronizing pulse, the stage remaining cut off between pulses due to grid-current biasing. A damped resonant anode circuit 35 "rings" to produce a waveform Y which constitutes the gating wave, the wave being effective to hold gate 51 cut-off by grid-current biasing so that it conducts only during an interval t 2 -t 3  when the wave exceeds cut-off level r. The interval coincides with a part of the "burst" interval so that a restricted portion Z of the "burst" appears in the anode circuit 59 and is from there applied to a phase detector system 18 for synchronizing the receiver subcarrier oscillator. Circuit 35 is suitably made resonant at a frequency of approximately 13 times line frequency. The flyback pulses applied at terminal 30 serve to prevent stage 34 from becoming conducting continuously with possible consequent damage (due to large space current) in the absence of synchronizing pulses. The pulses also render the stage immune to noise pulses between synchronizing pulses. The restrictive gating action of the invention serves to prevent spurious transients W, Fig. 2, which are caused by overshoots O due to receiver mistuning or band-pass characteristics, from interfering with the subcarrier synchronizing operation. Specification 781,178 is referred to in connection with the synchronizing system. Specification 738,922 also is referred to.

Title: Improvements relating to apparatus for supplying high frequency alternating electric current from a low frequency source
IPC: H02M5/00
Filed: 1924-07-28
Abstract: 240,954. Westinghouse Brake & Saxby Signal Co., Ltd., (Union Switch & Signal Co.). July 28, 1924. Thermionic generators for supplying high-frequency currents to a load circuit, such as the track circuit of a railway signalling system, have their plate circuits energized bv a low-frequency supply through a transformer which also serves to transfer the high-frequency currents to the load circuit; and filter devices direct the. two currents into the desired channels. Further valves may be employed for generating a different high frequency, or for amplification. As shown in Fig. 1, the plate circuit of the valve 1 is back-coupled to the grid circuit 7, 11 so as to generate alternating current at the frequency of this circuit. The grid circuit also includes a leak resistance 10 and condenser 6. The plate circuit is supplied from a low-frequency alternator 14 through a transformer 12. The current of higher frequency generated by the valve is taken off by a third coil 23 of the transformer and is supplied to the load 24. A filter or small condenser 25 blocks the supply frequency from the load 24, and a choke 17 blocks the higher frequency from the alternator 14. A separate high-frequency generator 26, Fig. 3, of any suitable type may be connected in the grid circuit instead of employing a back coupling; and a single coil 13, Fig. 3, may be used both as the low-frequency input coil and as high-frequency output coil, the two currents being kept to their proper paths by the choke 17 and condensers 25, 27. Fig. 5 shows a modification in which two separate valves 1<a>, 1<b> are used for generating two different high frequencies, which after amplification are supplied to the track rails C, D of a block section of a railway. A transformer 29 supplies the filament circuits of all the valves in parallel, and their plate circuits are supplied from a transformer 30, the mid-points of the two secondaries being connected together. One end of the secondary coil of the transformer 30 is connected through a filter inductance 17<a> to the plates of one generating valve 1<a>, and one amplifying valve 38<a>. The other end of the secondary coil of the transformer 31 is connected through a similar inductance 17<b> to the plates of the valves 1<b> and 38<b>. Thus for one half cycle of the supply, the plates of valves 1<a>, 38<a> are at a positive potential, and oscillations generated by the valve 1<a> are passed through the coupling 35a to the grid of the amplifier 38<a>, and the amplified currents in the plate circuit are transferred through the coupling 13<a>, 23 to the track rails C, D. During the alternate half-cycles, the other pair of valves are active and current of a different frequency is supplied to the track rails. The intermittent character of the high-frequency currents does not interfere with their employment for signalling. The amplifying valves 38<a>, 38<b> may be omitted.

Title: Manufacture of dyes
IPC: C09B43/08
Filed: 1943-11-01
Abstract: Fluorescent dyestuffs are manufactured by reducing a water-insoluble o-nitro-monoazo dyestuff free from sulphonic acid groups with an alkali metal or ammonium formaldehyde-sulphoxylate, and interrupting the reduction when a water-insoluble dyestuff which fluoresces under the action of ultra-violet light has been formed.  The reduction may be effected with aqueous solutions containing 0.5 to 15 per cent, preferably 10-15 per cent, by weight of formaldehyde-sulphoxylate and advantageously containing an organic solvent for the dyestuff, e.g. ethyl or butyl alcohol or dioxane, and is preferably carried out at raised temperatures such as 50-80 DEG  C., e.g. by refluxing an aqueous-alcoholic solution of the dyestuff and the formaldehyde-sulphoxylate for 1-3 hours.  The products may be applied to cellulose ester or ether textiles, e.g. cellulose acetate or propionate, mixed esters such as cellulose acetate-propionate or acetate-butyrate, or cellulose ethers such as ethyl or benzyl cellulose; or these materials may be dyed with the parent o-nitro-monoazo dyestuff and the reduction effected on the fibre, e.g. by the action of a 0.5 to 10 per cent aqueous solution of the formaldehyde sulphoxylate at 60-90 DEG  C. for 1/2 to 4 hours, or by padding the materials with an aqueous solution of the formaldehyde-sulphoxylate preferably containing a swelling agent for the cellulose ester or ether, drying and steaming, e.g. at 95-120 DEG C. for 5-40 minutes.  In examples: (1) an aqueous alcoholic solution of 6-chloro-2 : 4-dinitro-21-acetylamino-41 - di - (hydroxyethyl) - aminoazobenzene and sodium formaldehyde-sulphoxylate is refluxed for 3 hours; the product yields on cellulose acetate fabric a yellow dyeing which fluoresces blue-green in ultra-violet light; (2) and (3) 2 - nitro - 21 - acetylamino - 41 - di - (hydroxyethyl -aminoazobenzene and its 4-chloro-derivative similarly yield dyestuffs of similar properties; (4) a cellulose acetate fabric dyed red with 2 : 4 - dinitro - 41 - diethylaminoazobenzene is heated to 80 DEG  C. for 4 hours in an aqueous solution of sodium formaldehyde-sulphoxylate, producing a yellow shade which fluoresces blue-green in ultra - violet light. Specifications 319,308, [Class 2 (iii)], 411,096 and 543,901 are referred to.  The Specification as open to inspection under Sect. 91 (4) (a) comprises generally the reduction of o-nitroazo dyestuffs to fluorescent compounds, advantageously by means of a formaldehyde-sulphoxylate of alkaline reaction.  This subject-matter does not appear in the Specification as accepted.
